Christopher Nolan has revealed that The Dark Knight Rises will be his last Batman film.

When asked by MTV News if the movie would be his final one about the caped crusader, the director replied: "Yes".

Christopher, who had great success with the first two instalments, Batman Begins and The Dark Knight, also commented on his joy at the completion of the series. He said: "We're very much excited about really finishing a trilogy and giving a conclusion to our story. And that's what we're doing."

Christopher also defended the new castings of Anne Hathaway as Catwoman and Tom Hardy as Bane, saying: "Once you see the film in 2012 you will completely understand why they were the perfect choice for these characters."

However, when asked about any themes or concepts for the new Batman flick he remained tight-lipped, stating: "Wow, that's a tricky one. I actually don't have an answer for you today... I'm gonna have to really think about that."
